br>In Builder's Guides at version 2.5 and earlier there is a mistake in the parts list.

The correct parts should be:

R102 is 56K
R104 is 330K

Version 2.5 and earlier have these the wrong way around. The schematic is correct.

I am sorry for any confusion this may have caused. The mistake has been rectified in BG versions 2.6 and above.

The reason for this error is that the text on the board has been reversed. You will see that the usual order of left to right numbering has not worked with these two parts and that R104 is to the left of R102. Rest assured R102 and R104 are as labelled and their values are 56K and 330K respectively.
